Then, when you have gone ten or twenty miles through cornfields without having seen a living thing, no cow, no dog, scarcely even a bird under the hot sky, suddenly you come upon a noisy contraption at the roadside, a system of contraptions, rather, for husking the corn and stripping the grain.

当你穿行在玉米田间，行驶了十里，二十里，却看不到一个活物，看不到牛看不到狗，连晴热天空下的飞鸟也难见到，这时，突如其来地，你会见到路旁有个发出噪声的新奇的机械装置，或者说是一组机械装置，那是用来剥玉米壳碾谷的。

Light engine scanning is in the way of spurring reflects to circle with the machine unit. The rule is easy, sweep range greatly, yet the problem is that the machine system is the bad accuracy and the stability is harder domination and so on.

光机扫描是用机械装置驱动反射系统旋转以实现激光光束的扫描，其原理简单，扫描范围大，但机械系统存在机构精度差、稳定性较难控制等不足。

A mechanical device for engaging and disengaging gears.

用来结合和分解齿轮的机械装置。

They comprised astronomical kaleidoscopes exhibiting the twelve constellations of the zodiac from Aries to Pisces, miniature mechanical orreries, arithmetical gelatine lozenges, geometrical to correspond with zoological biscuits, globemap playing balls, historically costumed dolls.

161是的。就是要把纸枪、橡胶浮囊、掷骰子游戏和弹弓排斥出去；其中包括展示白羊宫乃至双鱼宫这十二宫星座的天体万花筒、小型机械装置的太阳系仪、算术用菱形果子冻、相当于动物饼干的几何图形饼干、游戏用地球仪皮球、身穿历史服装的玩偶。

Flow rate is measured at the detector outlet, either with a calibrated mechanical device or with a bubble tube, while the column is at operating temperature.

当在运行的温度下，流速在检测器出口，用标刻度的机械装置或用气泡法测量。

"Hydraulic safety valve" is widely used in hydraulic power systems and hydraulic equipment of safety devices, pressure devices can be limited, is a special valve, which is different from the conventional valve, the traditional use of mechanical valves metal spring as a driving force, can only be limited to low pressure, encountered more BALANCING VALVES than 10Mpa pressure limit pressure can do to increase the volume of pressurized design, the traditional role of the high-pressure valves and high pressure hydraulic power systems and hydraulic equipment The limit pressure of necessity is bulky and complicated structure, difficult to manufacture large, high production costs; in the course of the fatigue of metal spring parameters change fluctuating pressure limiting Ambassador to regular revision to ensure the normal use.

&气动液压安全阀&是目前广泛应用于液压动力系统和液压设备中的安全装置，也可以作限压装置，是一种特殊的阀门，它不同于传统的阀门，传统阀门用机械金属弹簧为动力，只能限中低压力，遇到超过10Mpa以上的压力限压，闸阀只能做加大体积的增压设计，因此传统阀门作用于高压和超高压的液压动力系统和液压设备的限压时必然体积笨重，结构复杂，制造难度大，产品成本高；在使用过程中金属弹簧的疲劳变化大使限压参数波动大，要经常调整才能保证正常使用。

"Hydraulic safety valve" is now widely used in hydraulic power systems and hydraulic equipment in the safety device could also serve as limited pressure device, is a special valve, unlike conventional valves, conventional valves with mechanical metal spring as a driving force, can only be limited to low pressure, the pressure encountered over more than 10Mpa limit pressure can do to increase the volume of the Safety Overflow Valve booster design, the traditional role of the high-pressure valves and high pressure hydraulic power systems and hydraulic equipment The limit pressure of necessity is bulky and complicated structure, difficult to manufacture large, high production costs; in the course of the fatigue of metal spring parameters change fluctuating pressure limiting Ambassador to regular revision to ensure the normal use.

Interest in hardware-based artwork with original design also is a key element in the activities of Maywa Denki, an "art unit" led by Nobumichi Tosa. [Fig. 1] Mixing lowtech and high-tech, he designs and manufactures strange looking robotic instruments that are performed by him or in collaboration with his "employees," or preprogrammed, or sold to enthusiastic Maywa Denkifans.

喜欢以硬体装置为艺术原创基调是明和电机创作的重要元素-由土佐信道领导的艺术团体，结合低科技与高科技，土佐信道设计并制造了看起来怪异的机械装置，让他或是他的员工或是明和电机用来表演。

Wire pull testing requires a special equipment commonly referred to as a wire pull tester, which consists of two major parts: 1 a mechanism for applying the upward pulling force on the wire using a tool known as a pull hook; and 2 a calibrated instrument for measuring the force at which the wire eventually breaks.

拉线测试所需设备：拉线测试设备，主要由两部分构成，1）由一机械装置驱动一拉钩产生一向上的拉力，2）经校准后的力度测试装置，用来测量金线从芯片表面拉开时的力度。
